In our previous blog post, “How to refresh browser, web page,” we talked about how to refresh you browser in order for users to see changes to a website.
“When we make changes to a clients’ website, they often don’t see the changes right away. This is because their browser (Internet Explorer, Firefox, Chrome, etc.) has cached web pages. When a browser caches a web page, it stores a local copy on the visitor’s computer. This speeds up the page load time so the visitor can view the information faster when they visit the page again.”
If you don’t immediately see changes made to the website, you may have to go the extra step of clearing your browser cache and cookies in addition to refreshing your web page.
Browser cache is a mechanism used in helping to speed up a website, while we browse. Browsers download page elements when we visit a site. Elements can include but are not limited to images, buttons, script files, etc. Those elements are stored in a cache folder. When we visit a site, the browser checks to see if those page elements are in it’s cache folder. If they are, then the browser does not have to download the same file element again. This speeds up web browsing.
A cookie is a small piece of software that a website may put on your computer. This allows websites to keep track of a user’s browsing session. If you’ve ever been to a website that made you log in, and then later returned to that website, you may notice that you did not have to log in again. This is because of the cookie.
The process of clearing your browser cache and cookies is different depending on which browser you are using. Find your browser below, and follow the instructions.
